SAKUYE MIYAKE, OF SAN FRANCISCO, CALIFORNIA.

TIME-ALARM.

Application filed March 18, 1915.

To all whom it may concern. Y

Be it known that I, SAKUYE MIYAKE citizen of the Empire of Japan, residing at San Francisco, in the county of San F rancisco and State of California, have invented certain new and useful Improvements in Time-Alarms, of which the following is a specification. This invention relates to alarm devices and more particularly to an improved Wrist watch accessory inwhich the alarm mechanism may be set to operate at a predetermined time to remind the wearer of a duty to be fulfilled or an act to be performed.

To this end the said invention consists in the construction and combination of parts to be hereinafter more particularly set forth and claimed.

In the drawings:-Figure 1 is an elevation of my improved time-alarm;' Fig. 2 is a rear elevation, the back of the watch having been removed; Fig. 3 is a fragmentary cross sectional view (greatly enlarged) illustrating the interior operating or control mechanism; Fig. 4 is an elevation of the complete device, the attaching means being shown extended; Fig. 5 is a plan view of a special type of bearing support; Fig. 6 is an edge view of said support; Fig. 7 illustrates a plan and side elevation of a novel type of spring; Fig. 8 shows fragmentary'views of certain specific parts; Fig. 9 is a detail perspective view of the stub shaft; and Fig.

10 is an elevation of the spring motor.

Like numerals of reference may be said to designate like parts throughout the several views.

Before proceeding with the description of the drawings I desire to call particular attention to the fact that while I have evolved my invention with refernce to its use as an improved wrist watch accessory or device, the same may be readily utilized in connec tion with a watch or time piece to be worn upon the ankle or other part of the body.

In the drawings, 1 designates an ordinary watch case equipped with suitable works of a character common to the art. The dial 2 however is arranged in spaced relation to the normal front face of the watch herein designated 3 that the operating mechanism, shown to advantage in Fig. 3, may be interposed therebetween. The minute hand of the watch, designated 4 is mounted to turn with the shaft 5, while the hour hand 6 is mount- Specification of Letters Patent.

ed to turn with the sleeve like structure 7, I

the said shaft 5 and said driven by the works (not shown) inclosed in the watch case 1. The sleeve like structure 7 is provided with a longitudinally extending key 8, said key, by reason of its lockmg engagement with a key way thereforformed in a cam face disk 9, imparting r0- tary movement to said disk yet permitting said disk to be moved or slid longitudinally as will hereinafter appear. The cam face of the disk is designated 10.

An indicator 11 is operable over the face of the dial 2, the indicator being movable to register with one or the other of the dial numerals, thereby indicating or designating the hour or exact time at which the alarm will be given. Said indicator 11 is made integral with a sleeve 12 arranged to embrace the sleeve like structure 7, the sleeve 12 being equipped at the end opposite from that from which the indicator 11 is formed with a disk 13 from the under face of which a pin 14; projects. The pin 14: is situated adjacent the periphery of said disk 13 and is mounted to ride upon the upper cam face of the cam-disk 9.

A novel. type of leaf spring, designated as an entirety by the numeral 15, is provided tomaintain cam disk 9 in positive engagement with the pin 14, said spring being affixed at one end as indicated at 16 to the casing part 3 and arranged to abut the oppostructure 7 being site face of the cam disk from that desig-.

nated 10. The shaft 5, in order that the spring may be held against lateral displacement, is arranged to penetrate the said spring, the opening for the shaft being shown at 17 in Fig. 7. spring 15 is inturned or extended at a right angle as noted at 18, the extension penetrating the watch face and projecting beyond the rear face of the watch to provide an abutment for the alarm hand indicated 19. Said alarm hand is equipped with a body contact member 20 (preferably of an arcuate formation) and is made fast at its fixed end to a threaded extension 21 of a stub shaft or spindle 22. Spindle is positioned concentric to the watch case or in axial alinement with shaft 5, aspecial type of bracket 23 in the nature of a bearing support afl'ording av suitable means for maintaining the spindle or stub shaft in place. The bearing support is of a spider formation, the re- The free end of thespective leg terminals being made fast as at 2-l to the watch case back.

Beneath the bearing support 23 is arranged aspring motor 25, the said motor including a suitable casing 26, spiral spring 27 and gear 28. The spring 27 is mounted within the casing 26, one end of the spring being made fast with the inner wall of the casing, the opposite end of the spring having connection with the stub shaft 22 for imparting movement to the hand 19 as will subsequently appear. The teeth of gear 28 are in mesh with the teeth of a comparatively small gear 29, the latter being situated in adjacent proximity to the winding stem 30 of the watch and having a suitable gear connection therewith whereby to provide for a winding of the spring motor immediately previous to a setting of the alarm device noted above.

If desired, the device may be provided with a lever 31 fulcrumed as at 32 intermediate its ends, the lever being movable as indicated in Fig. 2 to render the device operative or inoperative as occasion may de mand. Said lever is situated in the path of movement of hand 19.

In operation, the indicating element 11 is moved in such relation to the dial of the watch as to indicate the hour or time at which the alarm is given, movement of the element 11 positioning the pin 14: upon the cam-face 10 of the disk 9 as required. Movement is then imparted to the cam disk 9 by the driving force of the hour hand 6. As the hour hand is moved into parallelism with the indicating hand or element 11, pin 14 is caused by such movement to ride over the shoulder formed upon the cam face 10,

thereby permittingthe cam disk to move.

longitudinally of the sleeve-like structure 7, the moving force being derived through pressure generatedin leaf spring 15. It is to be understood of course that the spring motor 25 has been previously rendered operative by a winding operation old in the art. As disk 9 is moved by the tension of spring 15, extension 18 of said spring is withdrawn from engagement with the alarm hand 19, thereby causing the said hand to rotate dur ing unwinding of the spring 27 constituting the motor 25.

The outside back face of the watch is apertured as indicated at 33, the apertures being of arcuate formation and disposed to coincide with the body contact member 20 as it is revolved through movement of hand 19. As said hand is revolved, body contact member 20 will operate in the slot 33 to thus engage the wrist of the wearer and, by reason of the irritation created through its rapid turning movement indicate to the wearer the time at which he is to fulfil some obligation or perform some particular act.

area ta ing that the conditions concurrent with the adoption of my device will necessarily vary,

I desire to emphasize the fact that variousv minor changes in details of construction, proportion and arrangement of parts may be resorted to, when required, without sacrificing any of the advantages of my invention, as defined in the appended claims.

, Having thus fully described my invention, what'I claim as new and desire to secure by Letters Patent, is

1. In a time alarm, the combination with a time piece, of control mechanism associated with the time piece, a motor, a body contact member rotatable by the motor,, and a spring arm conjunctivelv utilizable as a means for actuating said control mechanism when the mechanism is in an operative position and as a means for directly engaging and releasably holding the body contact member in an inoperative position.

2. In a time alarm, the combination with a time piece including hour and minute hands, control means associated with the hour and minute hands and arranged at a predetermined time to move into an operative position, a spring arm for operatingthe control means when the latter is arranged in an operative position, a motor, a body contact member rotatable by the motor, and the free end of the spring arm being in engagement with the body contact member for releasing the contact member upon movement of the spring arm.

3. In a time alarm, the combination with a time piece including hour and minute hands, control means associated with the.

hour and minute hands and arranged to move at a predetermined time into an operative position, a spring arm normally exerting a pressure on the control means for actuating the control means when the control means has been arranged in an operative position, a motor, an arm rotatable thereby, a body contact member carried by the free end of the rotatable arm projecting through the time piece and engageable with the rotatable arm for releasing the arm simultaneously with the operation of the control means.

4. In a time alarm, the combination with a time piece, an alarm release cam operated thereby, a motor, a body contact member rotated by said motor, a spring arm with its free end engaging the body contact member to hold the motor against operation, said In testimony whereof I afiix my signature in presence of two witnesses.
